For a granular soil deposit, γ = 108.8 lb/ft3, w = 8%, Gs = 2.65.
a) Determine the void ratio, e, for this soil.
b) For this soil, it is determined that Dr = 70%. If emin = 0.57, what is emax for this soil? c) What would be the dry unit weight of this soil in its loosest state?
d) What would be the dry unit weight of this soil in its densest state?

Soil collected from the site is found to have γ t = 18.5 k N / m 3 , w % = 8.6 % γt=18.5kN/m3,w%=8.6%, and G s = 2.67 Gs=2.67. After a heavy rainfall overnight, 10 % 10% increase in the degree of saturation S r Sr was observed. Determine:
